CFMMEU condemn police raid, as union officer is released without charge

A police raid on the home of a high-ranking CFMMEU official has been condemned by the union as "something no family should ever experience."

The senior vice president of the CFMMEU Derek Christopher along with two woman, aged 44 and 52, were arrested at their Keilor Lodge home this morning, but have since been released without charge.

Mr Christopher is under investigation by federal and state police, The Age reported, stemming from allegations he received free labour and materials from building contractors that he used to renovate his family home.

Victoria Police Fraud and Extortion Squad along with officers from AFP Fraud and Anti-Corruption seized computers and paperwork as part of a 13-month investigation into building industry fraud.

Neighbors confirmed to 9News the house raided in Keilor Lodge belonged to Mr Christopher.

Mr Christopher, 44, and a 44-year-old woman who were arrested at a Keilor Lodge home and 52-year-old woman arrested at a Keilor property are now being interviewed.

The arrests are part of a joint investigation by Victoria Police and Australian Federal Police, who last month also interviewed six men and a woman over as part of this investigation.

"They were interviewed in relation to the offence of receipt/solicitation of a secret commission and are expected to be charged on summons," police said in a statement.

"Today's warrants form part of a 13-month investigation into individuals within the construction and building industry and the alleged provision of materials and labour in exchange for favouring contractors."

The CFMEU said in a statement that Mr Christoper had the right to the presumption of innocence but confirmed that the union official had previously "assisted the police with their enquiry."
